China Reports Over 90% Vaccination Rate
China has maintained a high vaccination rate under the country's immunization program above 90 percent, reported XinhuaNet.
This is important news since China, is a country with approximately 18 percent of the world's population.
China's immunization program requires vaccinations against diseases such as hepatitis B, poliomyelitis and measles for children.
According to the World Health Organization, China’s National Immunization Program is a government and academic organization. Its’ overall goal is to contribute to the control/elimination/eradication of vaccine-preventable diseases in China by raising awareness about the benefits of immunization and promoting the understanding and use of vaccines.
Dr. Gao said ‘a work team has been set up to analyze vaccine-related problems exposed over recent years to ensure effective solutions.’
According to a report published in The Lancet during August 2018, China experienced its “worst public health crisis in years” as stated by South China Morning Post.
Chinese vaccine maker Changsheng Biotechnology was found to have fabricated production and inspection records and to have arbitrarily changed process parameters and equipment during its production of freeze-dried human rabies vaccines.
Furthermore, substandard diphtheria, pertussis, and tetanus (DPT) vaccines produced by Changsheng Biotechnology were administered to 215,184 Chinese children; and 400,520 substandard DPT vaccines produced by Wuhan Institute of Biological Products were sold in Hebei and Chongqing.
Recently, the Columbia Mailman School published an analysis of China’s measles vaccination program.
Wan Yang, Ph.D., assistant professor of Epidemiology at the Columbia Mailman School, and lead author said in a press release, “The elimination of measles has been particularly challenging in China, the largest country with endemic measles transmission.”
“While since 2008 China has reported greater than the 95 percent vaccination target coverage for measles elimination, measles has continued to cause large outbreaks every year for reasons that remain undetermined,” said Wan Yang.
This study published in PLOS focused on Beijing, Guangzhou, and Shandong. To eliminate measles in these locations, a minimal population herd immunity of 93.8%, or with a vaccine efficacy (VE) of 95%, and minimal vaccine coverage of 98.7% [VT = (1–1/R0) ÷ VE = (1–1/16) ÷ 0.95] is needed to eliminate the measles disease.
Separately, the US Centers for Disease Control and Prevention (CDC), suggest various vaccinations prior to visiting China.
The CDC says you should be up to date on routine vaccinations and some vaccines may also be required to visit the country.
Ask your doctor or pharmacist which vaccines and medicines you need based on where you are going, how long you are staying, what you will be doing, and if you are traveling from a country other than the USA.
